Stub file for a guaranteed safe import of duecredit constructs:  if duecredit
is not available.

To use it, place it into your project codebase to be imported, e.g. copy as

    cp stub.py /path/tomodule/module/due.py

Note that it might be better to avoid naming it duecredit.py to avoid shadowing
installed duecredit.

Then use in your code as

    from .due import due, Doi, BibTeX, Text

See  https://github.com/duecredit/duecredit/blob/master/README.md for examples.
